Sepsis Characterization in Kilimanjaro — SICK  

Sepsis Clinical Trial

Official title: Sepsis in Sub-Saharan Africa: a Prospective Observational Study of Clinical Characteristics, Management, Outcomes, and Barriers to Care in Northern Tanzania

Status Completed

Clinical Trial Summary

The aim of this study is to prospectively evaluate the barriers to care, evaluation, clinical practices, and outcomes for patients presenting with sepsis to hospitals in the Kilimanjaro Region of northern Tanzania. This will include an assessment of timing and selection of antimicrobials and administration and volume of intravenous fluids. The study also aims to characterize sepsis sub-types in the epidemiologic context of northern Tanzania using statistical clustering techniques of clinical variables and of host immune response patterns.

Clinical Trial Description

A prospective observational cohort study of adolescent and adult patients with sepsis presenting to hospitals in the Kilimanjaro Region, Tanzania. Participants ≥10 years of age with suspected infection and the presence of two of the following will be enrolled: (1) tympanic temperature > 38°C or < 36°C, (2) heart rate > 90 beats/minute, (3) respiratory rate > 20 breaths/minute. Participants will be observed in the Emergency Department and during admission. The following data will be collected: demographics and medical history; history of present illness; laboratory and microbiological workup; antimicrobial selection and timing; intravenous fluid timing and volume. Vital status will be determined at 7 days, hospital discharge, and 28 days post-presentation. An enrollment of up to 1250 patients with sepsis is expected over a two-year period. This study is expected to produce additional descriptive data of sepsis epidemiology and current practice in sSA. The data will yield important insights regarding key care practices for sepsis, including antimicrobial and intravenous fluid management. Outcomes of patients with sepsis will be described, including an assessment for correlations between current care practices and mortality. Characterization of potential sepsis sub-types will be undertaken in two domains: 1) clinical characterization via a robust battery of routine clinical laboratories (chemistry, hematology, coagulation studies), vital signs, routine clinical signs and anthropometry; 2) host immune response characterization by analysis of mRNA transcriptome expression in RNA-stabilized whole blood samples. The goal of the sub-type characterization is to identity discrete and clinically relevant sepsis phenotypes, and in doing so eventually help optimize evaluation and management of sepsis specific to the populations and health systems in sub-Saharan Africa. Detailed etiologic investigations will also take place, including blood culture, blood parasite smears, and viral respiratory testing of nasopharyngeal samples; for patients living with HIV, additional evaluations will include serum cryptococcal antigen, urine lipoarabinomannan assay (TB-LAM) and MycoFLytic blood culture. Collectively, the data collected in this observational cohort study will contribute to further developing sepsis management bundles better suited to settings sub-Saharan Africa. ;
